Question

P the perimeter of a square and rectangle is 48 each the difference between the area of the two is 4msquare. Find the length and breadth of the rectangle

Answer 1

Answer:

Step-by-step explanation:

Perimeter of Square=4 X side

48= 4 X side

=48÷4=12

12 is the side of square

Area of square=side²

Area=12 X 12=144

It is given that area of rectangle is 4m² less than area of square

So area of rectangle=144-4=140

Let length=a

Breadth=b

(a+b)²=a²+b²+2ab

24²=a²+b²+2 X 140=280

576=a²+b²+280

296=a²+b²

14²+10²=296

So length=14

Breadth=10
